Just added these

It comes with 8 x 240mm lengths of track so that should be easily enough for all the cars, although I suspect most display cabinets would need to have them as two rows of track with the cars on them.  This seems to be a new thing to supply the track to display trains on as my Hitachi 800 LNER Azuma came with track suitable for displaying it also.  Of course as its normal Kato unitrack there's nothing to stop you using the track on your layout either
